ok i am going to test this as a metal detector, it only has 1 ADC just hook an opamp to it, I will be using it to set the pulse rate, sensitivity, I will see if there is any delay in sending a detect signal, if there is none you can use your mobile as a receiver, also some where there is an Arduino vdi project why not use this instead

I see musicians use an interface which has no appreciable delay to connect guitar to android for rack of effects.
